You may also get a cough and a mild fever. The symptoms usually build, peak, and slowly disappear. Some medications can ease symptoms. For example, decongestants may decrease drainage and open the nasal passages. Pain relievers may help with fever and headache. Cough medicine may help, as well.

Sometimes, a cold may cause swelling in the sinuses, hollow spaces in your skull that are connected to each other. The swelling can prevent the flow of mucus.

This can lead to a sinus infection. If you have pain around your face and eyes -- and thick yellow or green mucus for more than a week -- see your doctor.

What Is a Sinus Infection?

It's inflammation or swelling of your sinuses. Normally they're filled with air. When they become blocked and filled with fluid, bacteria can grow there and cause infection. The result: a sinus infection. You may hear your doctor refer to it as sinusitis.

Steam and hot showers can help you loosen mucus. Your doctor may also suggest nasal saline to wash mucus from your nose.

In rare cases, when a sinus infection doesn't go away, long-term antibiotics or surgery may be needed.

When Should I Call the Doctor About a Cold or Sinus Infection?

Most colds go away without medical treatment. If you have pain around your face or eyes, along with thick yellow or green nasal discharge for more than a week, check with your doctor. Also call him if you have fever or symptoms that are severe or don't get better with over-the-counter treatments.
